Tag Database and Communication

Effective tag management and PLC communication configuration form the foundation of reliable HMI operation. This section covers comprehensive tag database organization, communication setup, and data handling strategies for robust FactoryTalk View applications.

HMI Tags vs PLC Tags

Understanding Tag Relationships:

PLC Tags: Tags residing in Allen-Bradley PLC programs represent physical I/O, internal logic variables, and control parameters. PLC tags are created and managed in Studio 5000 Logix Designer with specific data types, scope, and external access properties.

HMI Tags: Tags in FactoryTalk View provide interface points to PLC data, local calculations, and temporary display values. HMI tags may directly reference PLC tags or contain independent values for user interface functionality.

Tag Categories:

Direct Reference Tags: Tags with addressing directly to PLC memory:

• Read PLC tag values for display
• Write operator inputs to PLC tags
• Bidirectional communication for setpoints
• Example: {Line1_PLC}MainProgram:Motor_Speed

Derived Tags: Tags calculated from other tags using expressions:

• Mathematical operations on PLC values
• Conversions (engineering units, scaling)
• Logical operations for complex indicators
• Example: (Tank_Level * Tank_Diameter * Tank_Height) / 1000 for volume

Memory Tags: Local HMI tags without PLC connection:

• Temporary display variables
• User interface state information
• Historical value storage

• Main Content Area: Process graphics and controls
• Footer/Status Area (60-80 pixels): Alarm summary, system status
• Navigation Column (optional): Left or right sidebar with menu

Color Standards: Implement consistent, meaningful color scheme:

Equipment Status Colors (ISA 101 Standard):

• Gray: Equipment off/disabled
• Green: Equipment running normally
• Yellow: Equipment in transition or warning state
• Red: Equipment faulted or emergency stopped
• Blue: Equipment under external control

Alarm Colors:

• Red: High priority, critical alarms
• Orange: Medium priority, urgent warnings
• Yellow: Low priority, advisory alarms

Background Colors:

• Dark Gray (RGB: 64,64,64): Reduces eye fatigue
• Light Gray (RGB: 192,192,192): Alternative for high ambient light
• Avoid pure white backgrounds (harsh on eyes)

Typography Standards: Readable text enhances usability:

• Display Titles: Arial Bold, 24-32pt
